Yahoo is enhancing its photo sharing platform, Flickr with the addition of a photo filter option to the Flickr mobile app, allowing users to add a number of different special effects to their images.

The photo-enhancing filters feature is now available on all of the major photo sharing apps, as users of Instagram (Facebook), Twitter and Snapseed (Google) have already grown accustomed to transforming their photos easily.

The new Flickr mobile app update also allows users to create custom filters, and even add 'live' filters while taking a photo.

Additional camera tools have also been added, including a grid display, pinch to zoom, better control of exposure points, and a focus lock. Finally, the app still offers all of the classic photo editing tools, including color and brightness adjustments, and the ability to crop images, for example.

The Flickr service provides users with a full 1TB of online photo storage.

The mobile app can be downloaded from the App Store (iOS) or from Google Play (Android).
